I was happy with the case... but note that it definitely will NOT work with the Yamaha MX49. I did the measurements and thought that since it appeared to be a soft case, it would flex enough for the keyboard to fit but that is impossible.

I took the case apart to alter it and make my keyboard fit (I don't recommend that). Under the fabric, the case is constructed out of styrofoam (like a cooler) and thin wooden slats. If you were to force an oversized keyboard into it that is too large, it would crack the styrofoam. There is no "give" to make it fit and with the MX49... I tried my best. I was able to make it work after altering the case but it took quite a bit of altering (peeling back the fabric, shaving away some styrofoam, and reaffixing the fabric).

Just wanted to mention that this really is a pretty full-on hard case in a soft nylon exterior ... which is great. It provides good solid protection for whatever is inside it ... which isn't the case at all for "soft" bags.The only down-side is, because it's a hard case, the listed dimensions can not be "fudged" like you can with a soft bag. The listed interior dimensions are in fact the maximum available ... so double-check the fit!
